  1. Kite Camera Group Members: Marc Bland Mark Burchill Walter Perry Robert Popovitch Andrew Theriault

  2. Presentation Outline • Existing Technology • Design Objectives and Goals • Components for Design • Cost Analysis • Schedule • Conclusions • Questions

  3. Existing Technology • Kite Aerial Photography (KAP) • Began with Hobbyist • Still-Photography • Simple suspension systems

  4. Design Objectives and Goals • Design a controllable aerial photography system to accurately capture pictures and video • construct suspension and cradle system • maximize range of motion with motors/electronics • Live streaming video

  5. Components for Design • Kite • Camera Cradle • Cradle Suspension • Camera • Video Transmission • Pan & Tilt Controls

  6. Kites • Winged-Box • Stable in heavy winds due to it’s boxed frame • Flies in light winds due to its’ winged design • Rokkaku • Solidly built • Adjustable tensioning • Winds ranging from 4-8 mph

  7. Kite Selection • Parafoil • Steady and easy to control • Inexpensive • Easily assembled • Excellent lift • Winds ranging from 8-25 mph • 17 square feet

  8. Cradle System • Cradle design crucial for maximum camera control • Goal to obtain pan and tilt motions • Critical Design Characteristics • Center of Gravity • Range of Motion • Support Type

  9. Cradle Design Types • LL Design • Most simple design • Lightweight • Supports only smaller cameras • Smaller range of motion • Tilting/Rotating motion

  10. Cradle Design Types • UU Design • Little more supportive • Capable of heavier weights • Similar range of motion • Tilting/Rotating motion

  11. Cradle Design Types • UU Hover Variation Design • Most complex • Largest range of motion • Capable of horizontal and vertical rotations as well as tilting

  12. Cradle System Designs

  13. Suspension Types Pendulum Picavet

  14. Pendulum • Made of two rigid tubes • Hard to control camera’s movements • Uncontrollable swinging leads to inaccurate and blurry pictures

  15. Picavet • Contains a self-leveling platform that resists rotation • Suspension line attached various ways • Small cross resists rotation better than a large one

  16. Attaching the Picavet Cross to Line • Ball bearing • Pulleys • Eye holes • Cord locks

  17. Attaching the Suspension to the Kite • Prussik Knot • Line Tree • Brooxes Hangup

  18. Threading the Line Threading SequenceA1 - 1 - B1 - R - 4 - A2 - R - 2 - B2 - 3 - A1.

  19. Cameras • Snap Shot • Takes still images • Blind shots • Smaller • Video • Allows for live streaming video • More expensive

  20. Digital Video Cameras • JVC GR-D70U • 16x optical zoom • Sports mode • Li ion battery • Mustek DV 5500 • Lightweight • Cost effective ($100) • Li ion battery

  21. Video Transmission • Types • Fiber Optic Cable • Wireless RF Transmitter • S-Video Cable

  22. Fiber Optic Transmitter • Includes a transmitter and receiver • Power supply needed for transmitter

  23. Wireless RF Transmitter • Includes a transmitter and receiver • No mess with wires • Quality may not be great

  24. Pan and Tilt Controls • Controlled by PIC (Peripheral Interface Controller) • PIC16F873

  25. Pan and Tilt Controls • PIC will be wired up kite line to power 180O and 360O servo and/or stepper motor attached to the camera cradle

  27. Schedule

  28. Conclusion • Integrated systems of Kite Camera • Funding is a possible problem • Testing and experimentation is vital

  29. Questions?
